Crystal Report如何消除详细信息部分中的重复数据？

Question

我创建了一个包含2个表中的字段的报表，但是CR自动复制了“详细信息”部分中的数据，这在a **中很麻烦。有什么方法可以消除这种行为？

到目前为止，这是我的代码：

Dim reportsfolder As String = Application.StartupPath + "\PrintArea\"

            Dim comand As New SqlDataAdapter("SELECT JV.DateEntry, JV.Explanation, JVD.* FROM GeneralJournal JV LEFT JOIN GeneralJournalData JVD ON JV.ReferenceCode = JVD.ReferenceCode WHERE JV.ReferenceCode = '" & MetroLabel4.Text & txtJV.Text & "' AND JVD.Code <> ''", jonsqlcon)
            Dim cmtable As New DataTable
            comand.Fill(cmtable)

            Dim cryRpt As New ReportDocument
            cryRpt.Load(reportsfolder + "PrintGeneralJournal.rpt")

            ''''for dblogin
            Dim crTable As CrystalDecisions.CrystalReports.Engine.Table
            Dim crTableLogonInfo As CrystalDecisions.Shared.TableLogOnInfo
            Dim ConnInfo As New CrystalDecisions.Shared.ConnectionInfo()

            ConnInfo.ServerName = tmpSN
            ConnInfo.DatabaseName = tmpDBN
            ConnInfo.UserID = tmpUID
            ConnInfo.Password = tmpPass

            ClientViewer.CrystalReportViewer1.ReportSource = Nothing

            cryRpt.SetDataSource(cmtable)

            For Each crTable In cryRpt.Database.Tables
                crTableLogonInfo = crTable.LogOnInfo
                crTableLogonInfo.ConnectionInfo = ConnInfo
                crTable.ApplyLogOnInfo(crTableLogonInfo)
            Next

            cryRpt.SetParameterValue("CompanyName", cname)

            ClientViewer.CrystalReportViewer1.ReportSource = cryRpt
            ClientViewer.CrystalReportViewer1.LogOnInfo(0).ConnectionInfo.IntegratedSecurity = True
            ClientViewer.CrystalReportViewer1.Refresh()
            ClientViewer.ShowDialog()

也请查看输出结果
